BELLWORK TN READY Review: 1Bellwork per day 1Homework question per day Due every FRIDAY 2-STEP EQUATIONS 7. EE.4 Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. 7. EE.4a. Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. REVIEW: GEBRA/TWOSTEPEQUATIONS/ STEPS 1.Circle the number that is not attached to the variable Use inverse operations 2. Solve One-Step Equation Inverse operation to isolate the variable Write solution as x=___ GUIDED PRACTICE Example: 2x + 9 = 23 1.What is not attached to the variable? 2.Isolate the variable 3.Solve! GUIDED PRACTICE Example: 29 = -3x 4 1.What is not attached to the variable? 2.Isolate the variable 3.Solve!

GUIDED PRACTICE Practice BELLWORK Homework: Day 1 Practice **For a GRADE** 2-STEP PRACTICE What is the 2 nd step in solving the following equation? x 5 = 10 PARTNER PROBLEMS Each person solves their problem and checks with their partner. Solutions should match. If not check each others work to find the error.

EE.4 Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. 7. EE.4a. Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. A square has a perimeter of 40 with each side length measuring 2x 6. Write and solve an equation to find x. STEPS Step 1: What is the variable (what do we not know) Step 2: What is the answer in the equation Step 3: Set up equation Step 4: Solve equation Step 5: Reread problem to make sure your answer makes sense SETTING-UP THE EQUATION Example : A new one year membership at the YMCA costs $160. A registration fee of $28 is paid up front and the rest is paid monthly. How much do new members pay each month? Step 1: What is the variablewhat do we not know? - x = monthly fee Step 2: What is the answer in the equation - costs $160 so =160 Step 3: What information is given that is a set amount? (paid once) Step 4: Set up equation -registration fee plus 12 times monthly cost is $ x = 160 Step 5: Solve equation Step 6: Reread problem to make sure your answer makes sense QUESTION CARD 1 The school purchased baseball equipment and uniforms for a total cost of $1,836. The equipment costs $612, and the uniforms were $25.50 each. How many uniforms did the school purchase? Write and solve the equation. CARD 2 A cell phone plan charges $1.01 for the first 25 texts sent or received on a phone and then $0.09 for each additional text per month. A monthly bill for texting was $9.56. How many extra texts were made that month? Write and solve the equation. CARD 3 CARD 4 CARD 5 WHEN FINISHED: TRY Jessie was playing a board game with four of his friends. He was doing well until he landed on a railroad and lost half of his money. Then on his next turn he landed in jail and had to pay each friend $250 in order to get out of jail. Jessie now has $100. How much money did Jessie have before he landed on a railroad? 1. Identify all the parts of the problem including the unknown. 2. Write and solve an equation 3. Model the equation or solve a different way. 4. Explain your work. BELLWORK Homework: TN READY Homework due tomorrow 2-Step Equation Worksheet due tomorrow P(X+Q)=R OR PX + Q=R 7. EE.4a.
